The influence to the impact strength of the recycled rubber granules addition on the concrete structural elements

Abstract

Concrete building elements having modified mixes improved the physic properties and mechanical characteristics (strength) of the material. However, the role of the rubber recycled granules addition should not be reduced only to this principle (strengths improvement), but also, to control the cracking’s process evolution and, thereby, to energy absorption properties and impact resistance, shock, temperature variations, to fire resistance. The present paper offered specialists, a new approach to achieve concrete mixes with recycled rubber granules from waste tires, that could solve two major problems in this field: improving the impact/shock resistance of concrete’s structural elements, as well as the environmental pollution refinement (by non-biodegradable items) through its integration into construction materials.
